STAMFORDHCI634H STAMFORD SPECIFICATIONS & OPTIONS STANDARDS Newage Stamford Industrial generators mest tne requirements of BS EN 60034 and the relevant section of other interational standards such as 885000, VDE 0530, NEMA MG1-32, IEC34, CSA €22.2-100, AS1359. Other standards and certifications can be considered on request. VOLTAGE REGULATORS. MX321 AVR - STANDARD This sophisticated Automatic Voltage Reguiator (AVR) is incorporated into the Stamford Permanent Magnet Generator (PMG) system and is fited as standard to generators ofthis type. The PMG provides power via the AVR to the main exciter, giving a source of constant excitation power independent of generator output. The main exciter output Is then fed to the main rotor, through a full wave bridge, protected by a surge suppressor. The AVR has in-built protection against sustained over excitation, caused by internal or extemal faults. This de-excites the machine after a minimum of 5 seconds. (Over voltage protection Is builtin and short circuit current level adjustments is an optional facity WINDINGS & ELECTRICAL PERFORMANCE. All generator stators are wound to 2/3 pitch. This eliminates triplen (3rd, 9th, 18th ...) harmonies on the voltage waveform and is found to be the optimum design for trouble-free supply of non-linear loads. The 23 pitch design avoids excessive neutral currents sometimes seen with higher winging pitches, when in parallel with the mains. A fully connected damper winding reduces. oscilations during paralleling. This winding, with the 2/8 pitch and carefuly selected pole and tooth designs, ensures very low waveform distortion, TERMINALS & TERMINAL BOX Standard generators feature a main stator with 6 fends brought out to the terminals, which are mounted on the frame at the non-drive end of the generator. A sheet steel terminal box contains the AVR and provides ample space for the customers’ wiring and gland arrangements. It has removable panels for easy access, SHAFT & KEYS. All generator rotors are dynamically balanced to better than BS6861:Part 1 Grade 2.6 for minimum vibration in operation, Two bearing generators are balanced with a half key. INSULATION/IMPREGNATION The insulation system Is class " All wound components are impregnated with materials and processes designed specifically to provide the high bulld required for static windings and the high mechanical strength required for rotating components. QUALITY ASSURANCE Generators are manufactured using production procedures having a quality assurance level to BS EN ISO 9001. The stated voltage regulation may not be maintained in the presence of certain radio transmitted signals. Any change in performance will fll within the limits of Criteria 'B' of EN 61000-6-2:2001. At no time will the steady-state voltage regulation exceed 2%. NB Continuous development of our products entitles us 10 change specification detalis without notice, therefore they must not be regarded as binging, Front cover crewing tylcal of product range.HCI634H STAMFORD WINDING 312 [CONTROL SYSTEM lave VOLTAGE REGULATION [SEPARATELY EXCITED BY PMG. x2 £05% With 4% ENGINE GOVERNING [SUSTAINED SHORT CIRCUT JREFER TO SHORT CIRCUIT DECREMENT CURVES (page 7) INSULATION SYSTEM PROTECTION RATED POWER FACTOR \sTATOR WINDING lwinoING PrTcH lwiNDING LEADS CLASH P23 08 DOUBLE LAYEs LAP.
